Graph Neural Network-Based Bandwidth Allocation for Secure Wireless Communications
Xin Hao, Phee Lep Yeoh, Yuhong Liu +3
This paper designs a graph neural network (GNN) to improve bandwidth allocations for multiple legitimate wireless users transmitting to a base station in the presence of an eavesdr…
Information Leakage in Index Coding With Sensitive and Non-Sensitive Messages
Yucheng Liu, Lawrence Ong, Phee Lep Yeoh +3
Information leakage to a guessing adversary in index coding is studied, where some messages in the system are sensitive and others are not. The non-sensitive messages can be used b…
Information Leakage in Index Coding
Yucheng Liu, Lawrence Ong, Phee Lep Yeoh +3
We study the information leakage to a guessing adversary in index coding with a general message distribution. Under both vanishing-error and zero-error decoding assumptions, we dev…
Information Leakage in Zero-Error Source Coding: A Graph-Theoretic Perspective
Yucheng Liu, Lawrence Ong, Sarah Johnson +3
We study the information leakage to a guessing adversary in zero-error source coding. The source coding problem is defined by a confusion graph capturing the distinguishability bet…
Random Shifting Intelligent Reflecting Surface for OTP Encrypted Data Transmission
Zijie Ji, Phee Lep Yeoh, Gaojie Chen +5
In this paper, we propose a novel encrypted data transmission scheme using an intelligent reflecting surface (IRS) to generate secret keys in wireless communication networks. We sh…
Secure mm-Wave Communications with Imperfect Hardware and Uncertain Eavesdropper Location
Saeed Mashdour, Majid Moradikia, Phee Lep Yeoh
This paper examines the secrecy performance of millimeter-wave (mm-Wave) communications with imperfect hardware and uncertain eavesdropper location. We consider a multiple-antenna…
Optimal Detection Interval for Absorbing Receivers in Molecular Communication Systems with Interference
Trang Ngoc Cao, Nikola Zlatanov, Phee Lep Yeoh +1
We consider a molecular communication system comprised of a transmitter, an absorbing receiver, and an interference source. Assuming amplitude modulation, we analyze the dependence…
Fractionally-Spaced Equalization and Decision Feedback Sequence Detection for Diffusive MC
Trang Ngoc Cao, Vahid Jamali, Nikola Zlatanov +3
In this paper, we consider diffusive molecular communication (MC) systems affected by signal-dependent diffusive noise, inter-symbol interference, and external noise. We design lin…
Chemical Reactions-based Detection Mechanism for Molecular Communications
Trang Ngoc Cao, Vahid Jamali, Wayan Wicke +4
In molecular communications, the direct detection of signaling molecules may be challenging due to a lack of suitable sensors and interference in the environment. Motivated by rese…
Diffusive Mobile MC with Absorbing Receivers: Stochastic Analysis and Applications
Trang Ngoc Cao, Arman Ahmadzadeh, Vahid Jamali +4
This paper presents a stochastic analysis of the time-variant channel impulse response (CIR) of a three dimensional diffusive mobile molecular communication (MC) system where the t…
A Code Equivalence between Secure Network and Index Coding
Lawrence Ong, Jörg Kliewer, Badri N. Vellambi +1
A code equivalence between index coding and network coding was established, which shows that any index-coding instance can be mapped to a network-coding instance, for which any ind…
Full-Duplex Cooperative Cognitive Radio Networks with Wireless Energy Harvesting
Rui Zhang, He Chen, Phee Lep Yeoh +2
This paper proposes and analyzes a new full-duplex (FD) cooperative cognitive radio network with wireless energy harvesting (EH). We consider that the secondary receiver is equippe…
An Equivalence Between Secure Network and Index Coding
Lawrence Ong, Badri N. Vellambi, Jörg Kliewer +1
We extend the equivalence between network coding and index coding by Effros, El Rouayheb, and Langberg to the secure communication setting in the presence of an eavesdropper. Speci…
Secure Index Coding: Existence and Construction
Lawrence Ong, Badri N. Vellambi, Phee Lep Yeoh +2
We investigate the construction of weakly-secure index codes for a sender to send messages to multiple receivers with side information in the presence of an eavesdropper. We derive…
